Summary: We just moved into a new house with hardwood floors. We have two australian shepherds. I choose this vacuum based on reviews from other people with hardwood floors and pets. When vacuuming carpet or hardwood all the pet hair catches in the roller and has to be constantly cut off and removed. It is hard to roll on the carpet, easy on the hardwood but does not pickup the hair on the hardwood. If my husband hadn't thrown out the box I would send it back.
